1-Phosphafulvenes are unique in their cycloaddition reactions, which act as 2π, 4π, and 6π systems and provide versatile and powerful approaches to various polycyclic systems. The reaction of 1-phosphafulvene with 1,4-benzoquinone and N-phenylmaleimide upon heating provided phosphapolycyclic rings in moderate to good yields. The possible mechanism included an oxidative addition of 1-phosphafulvene with 1,4-benzoquinone and successive Diels-Alder reactions with N-phenylmaleimide. The exocyclic C=C bond of 1-phosphafulvene is cruial to this reaction.

Key words: phosphafulvene, 1,4-benzoquinone, oxidative addition, cycloaddition
